(17.5 mph hand speed average). Began in a balanced open stance with a tight load, then used a closed small stride. Bat speed is developing, displays a flat loose swing plane and a front foot finish. Found a few barrels with loud contact. Gap to gap approach. Capable while in the infield, made throws up to 74 mph; has developing feet, developing soft hands, and a natural exchange. Movements laterally were developing and he fields the ball out front. Used a high ¾ slot and a consistent arm action. During the event, recorded a 60 time of 8.7. Capable on the mound, showed developing arm speed with a high ¾ arm angle and a short consistent arm action. Feel type pitcher and uses some effort. Has a consistent balance point and in line shoulders. Lands closed with a falling off finish. Sat with his fastball at 72-73 mph; had running action and command arm side around the zone. (Max spin 2004; Avg 1936). His curveball (62-64) showed glove side control and sweeping action. (Max spin 1881; Avg 1817). Straight changeup (68-69).
